Description

Technical Field

[0001] This patent relates to the field of heat exchange equipment, and in particular to a heat exchanger inlet air pre-cooling wet film and water retaining and diversion device. Background Art

[0002] In the field of heat exchange equipment, heat exchangers are important equipment that transfers heat from one medium to another through heat transfer to meet different process requirements. In the field of refrigeration systems, heat exchangers are an indispensable part of refrigeration systems. They achieve refrigeration effects by exchanging heat with refrigerants. In the field of wet film treatment technology, wet film is an efficient evaporative cooling technology that absorbs heat from the air through the evaporation of wet film to achieve a cooling effect.

[0003] In the prior art, the heat exchange capacity of the heat exchanger can be improved by adding a wet film on the outer surface of the heat exchanger. This method can effectively improve the heat exchange capacity of the heat exchanger, thereby improving the efficiency of the refrigeration system. However, it is usually impossible to avoid water droplets on the wet film entering the unit, causing corrosion of the unit and seriously affecting the life cycle of the unit. Summary of the invention

[0004] In view of this, the present application provides an air intake pre-cooling wet film, comprising: a wet film, which is a rectangular plate-shaped structure, and the wet film is placed vertically; a water collecting tray, which is arranged below the wet film; a spray diversion chamber, which is arranged above the wet film, and a diverter is arranged in the spray diversion chamber; a water retaining and guide assembly, which is in the form of a sheet, and its front side covers the back side of the wet film; a fixed plate assembly, which is two symmetrical sheet metal parts, which are arranged on the water collecting tray and respectively cover the two side end surfaces of the wet film, and the fixed plate assembly is used to fix the wet film and the water retaining and guide assembly; a top cover sealing plate, which is arranged on the upper end surface of the spray diversion chamber, so as to cooperate with the fixed plate assembly to make the air intake pre-cooling wet film an integral structure.

[0005] By adopting the above specific structure, a water retaining and guiding assembly is arranged behind the wet film, which can prevent excess moisture on the wet film from being brought into the heat exchanger by the airflow, thereby protecting the sheet metal parts in the unit from rusting, and increasing the service life and safety of the unit.

[0006] As a possible implementation, the water retaining guide assembly includes a plurality of guide blades, each of which is in the shape of an elongated strip. The plurality of guide blades are distributed in parallel on the water retaining guide assembly, and the guide blade has a recess, the recess extends a first extension portion in a direction perpendicular to the front side of the fixed plate assembly, and the recess extends a second extension portion in a direction perpendicular to the back side of the fixed plate assembly, a plurality of first water retaining strips extend obliquely downward from the lower end of the recess, and the second extension portion extends a second water retaining strip in the opposite direction of the extension direction of the first water retaining strip. A limiting portion is provided at the top end of the water retaining guide assembly, and the cross-sectional length of the limiting portion is not less than the cross-sectional length of the guide blade.

[0007] Using the above possible implementation method, the recessed portions in the multiple guide blades, the first extension portion, the second extension portion, the first water retaining bar and the second water retaining bar form a reverse scale spoiler structure. This structure is similar to the arrangement of the reverse scales of fish. When large particles of water enter with the airflow, the flow direction will be changed under the action of this special structure, and thus be collected in the recessed portion.

[0008] As a possible implementation, guide grooves are respectively provided at both side edges of the water retaining and guide assembly, and a drainage sponge is provided in the guide groove, and the drainage sponge is in contact with the plurality of guide blades.

[0011] By adopting the above possible implementation method, the water sprayed by the diverter first enters the diverter sponge before entering the wet film. The diverter sponge can form a uniform diverter surface, which plays a role in refining the particle size of the wet film flow.

[0012] As a possible implementation method, one end of the diverter is fixed on the spray diverter chamber, and the other end of the diverter is connected to an external water source. The diverter is provided with multiple spray holes. Through the multiple spray holes, the diverter can effectively spray water on the diverter sponge.

[0016] As a possible implementation manner, a side end surface or a bottom end surface of the water collecting tray is provided with a drainage hole or a drainage pipe for draining the accumulated water in the water collecting tray.

[0017] As a possible implementation, the wet film is made of organic polymer or inorganic polymer material in one piece; the diversion sponge and the drainage sponge are made of polyester polyol and polyisocyanate materials. BRIEF DESCRIPTION OF THE DRAWINGS
